Couldn't a guy wire up a generic tach that would register on our Cubs and then take the face off and print/install a new label so it "reads" correctly? For
example (accurate numbers are not about to be recited), a tach for a V6 would read 1/3 of what our engines are actually at. So, take the face off, print a new label that's adjusted for the 1/3 difference, and violla; a single cylinder tach. K.I.S.S., right?
